Parker FAFS-42 Female Straight Adapter 1/4 in Tube Od

Product Description

The PARKER FAFS-42 is a compression tube female straight adapter designed for use in fluid and pneumatic line assemblies requiring a reliable, chemically resistant tube-to-female connection. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting handles aggressive media where standard thermoplastic or metal fittings would degrade. It accepts a 1/4 inch tube outside diameter and uses a plastic grip-type compression mechanism to secure the tubing without requiring additional tools or sealants. The FAFS-42 is a practical choice for instrumentation, chemical processing lines, and specialty HVAC or refrigeration sampling applications where corrosion resistance and low friction are priorities.

This adapter is suited for both light industrial and laboratory environments where PFA or PTFE tubing is routed into female-threaded ports. Typical applications include chemical dosing systems, analyzer sample lines, and fluid handling setups found in commercial HVAC, water treatment, and process control installations. The straight adapter configuration allows for an in-line connection with minimal flow restriction. It is sold individually and installs quickly into compatible female-threaded fittings or port bodies.

Key Features

• PFA and PTFE construction provides broad chemical resistance and low extractables
• Accepts 1/4 inch tube outside diameter via plastic grip-type compression mechanism
• Female straight adapter configuration enables direct in-line tube-to-port connections
• Lightweight at 0.05 pounds, suitable for space-constrained instrument panels and manifolds
• No sealants or special tooling required for assembly under typical service conditions

Compatibility

Designed as an OEM-style compression fitting for use with 1/4 inch OD PFA or PTFE tubing in female-threaded port applications typical of fluid handling and instrumentation systems.

Installation Notes

Installation is performed by qualified plumbing, instrumentation, or HVAC technicians. Depressurize and isolate the line before removing or installing compression fittings. Hand-tighten the compression nut to seat the tube, then advance per the fitting manufacturer's standard procedure without overtightening, as PFA and PTFE components can deform under excess load. Verify tubing is cut square and fully inserted to the tube stop before completing the connection.
